The call with Vladimir Putin came as Ukrainian President Volodymyr Zelensky said publicly he wanted to discuss weapons supplies with President Trump.

President Trump said on Thursday that a phone call with President Vladimir V. Putin of Russia had not resulted in any movement toward ending the war in Ukraine, adding that he was “not happy” with the conflict grinding on. “I didn’t make any progress with him at all,” Mr. Trump told reporters.

The U.S. president urged Russia’s leader to quickly end the war in Ukraine, according to a Kremlin briefing on the hourlong call.
